1. Preheat oven to 350F and grab a baking dish large enough for 4 enchiladas. Pre-cook the chopped sweet potato, by simmering it in a small pot of water for about 5-10 minutes until just tender. Do not overcook. Drain and set aside.
2. In a large skillet or pot, add 1 tbsp oil and bring to medium to low heat. Add in the chopped onion and cook for about 5 minutes, stirring often, until translucent. Add in garlic and reduce heat to low and cook for a couple more minutes. Now add the chopped pepper, pre-cooked sweet potato, drained black beans, and chopped spinach. Cook for about 5-7 more minutes on medium-low heat.
3. Now add in your enchilada or pasta sauce. Stir well, and add in your seasonings: nutritional yeast (optional), cumin, fresh lime juice, salt, garlic powder, chili powder- all to taste. Adjust seasonings if necessary. Stir well.
4. Scoop about 3/4-1 cup of the mixture onto the bottom of your casserole dish and spread out in a thin layer. Scoop about 1/2-3/4 cup of the mixture onto each tortilla and wrap, placing the fold down on the casserole dish. Repeat for the remaining 3 tortillas and leave a bit of filling left to spread over the top. Sprinkle with vegan cheese if preferred.
5. Bake tortillas at 350F for 18-20 minutes. Meanwhile, make your Cilantro cream sauce (see below). When enchiladas are cooked, remove from oven and pour the sauce over top. Garnish with chopped cilantro and green onion. Serve immediately. Makes 4 enchiladas.

Note: Depending on what kind of sauce you use, you will have to adjust the seasonings to taste. I used a pasta sauce so I likely needed more seasonings to achieve the taste I desired.
